Subject: State Stormwater Permit No. SW8 080728
TECOM (SIO) Interim Facilities, MCB, CLNC — Camp Geiger
High Density Commercial Wet Pond Project
Onslow, County
Dear Mr. Baker:
The Wilmington Regional Office received a complete State Stormwater Management Permit
Application for TECOM (SIO) Interim Facilities, MCB,CLNC — Camp Geiger on July 22, 2008.
Staff review of the plans and specifications has determined that the project, as proposed, will
comply with the Stormwater Regulations set forth in Session Law 2006-246 and Title 15A
NCAC 2H.1000. We are forwarding Permit No. SW8 080728 dated July 28, 2008, for the
construction of the subject project.
This permit shall be effective from the date of issuance until July 25, 2018, and shall be subject
to the conditions and limitations as specified therein. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system will result in
future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within sixty (60) days
following receipt of this permit. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such demands
are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please
contact Malcolm Boney, or me at [phone].

Frank,
Thanks for getting me the permit number. I talked to Linda re # 2 below. The use of a liner appears to
be some what site specific. If the SHWT is more than 2 ft below the bottom of the storage basin, then a
liner is not necessarily needed (any escaping water will be effectively treated by infiltration). However, if
the SHWT is greater than 2 ft below the bottom of the storage basin, then some sort of liner is required.
As I mentioned to Mr.Upchurch on the phone, the type of baffle isn't something we typically look at.
We leave that up to the BPJ of the design engineer.
If you are just proposing material changes, than a modification isn't necessary. However, I would
recommend submitting a plan revision (free in the Regular program). If the BMP design (vol,
elevations, etc) or the amt of BUA/drainage area is changing, then a modification will be needed.
Let me know if you have additional questions.

We permitted a few months ago a high density permit for Camp Geiger one of the TECOM SOI Temporary
Facilities. There was a collection area for the stormwater and we were pumping it to a stormwater pond.
We would like to change a couple of items and need to know if it would require a modification to the permit.
1. Change the baffles in the pond from the pilings to a PVC bulkhead system.
2. Remove the concrete liner in the collection area and just use a stabilized bottom and sides.
If you need any other information please call me at your earliest convenience.

Dear Mr. Thompson:
Land Management Group, Inc. recently evaluated the above referenced site between
Church Street and A Street for the purpose of quantifying the depth to the seasonal high
water table for a proposed storm water infiltration basin. This investigation looked at the
property approximately 60 feet north of the drainage feature and approximately 120 feet
south of the drainage feature 1 offer the following comments.
The soils at this site are mapped as Goldsboro as referenced by the USDA-NRCS. Soil
Survey Manual for Onslow County. This soil series typically consists of well drained to
moderately well drained tine loamy soils. The seasonal high water table is normally
evident by observation of redoximorphic features suggesting past conditions of saturation
and reduction. Six soil borings were perfornied down to 4 feet in the proposed infiltration
basin area. The site was determined to not be a typical Goldsboro soil but was actually
an old flood plain of a creel: that has recently been filled and channeled during the course
of development of the Marine base. "['here was evidence of ns much as 18" of man made
fill in places and other locations showed evidence of being pushed and pulled with heavy
equipment in the past. The contemporary redoximorphic featttt'CS were ohscrved bctwf n
12" and 20" within the soil profile indicating a shallow depth to the seasonal high kvit V�
table. Furthermore, the surficial soil horizons (sandy, coarse loamy and tine loanry. oils)
were underlain by a nlnssivc clay layer at depth that may impair infiltration and will JUL 2 2 2008
rciluire lower infiltration rates. By.
In sununarv. the north side of the drain should be excluded from consideration ❑s a storm—_"
water infiltration basin due to fill and shallow water tables. The soils that begin
approximately 60 to 7.5 feet to the south of the drain, extending uphill to 120 feet from the
drain just barely meet the minimum criteria for use as a stormwater infiltration basin. A
basin in this area would need to be based upon a 12" depth to the seasonal high water
table and would therefore he an elevated infiltration basin. For design purposes, I would
recommend using a 2 in/hr infiltration rate for these soil types. Please do not hesitate to
contact me if you have any questions with this report ort if you want me to return to the
